我有一個測試檢查我使用 H2 進行測試的最后插入的 id@Entity@Datapublic class Guy implements Serializable {  @Id  @GeneratedValue(strategy = GenerationType.IDENTITY)  @Column(nullable = false)  protected Long id;  @Column(nullable = false)  protected String name;}這是測試@Testpublic void getTest() {  String jsonResponse = "{\"name\":\"andrew\"}";  Response response = given().body(jsonResponse).header("Content-Type",  "application/json").header("Client", 123).post("/thin/guy");  assertEquals(HttpServletResponse.SC_CREATED,response.getStatusCode());  //here the record was created  JSONObject jsonObject = new JSONObject(response.getBody().print());  Response resGet = given().header("Client",123).get("/thin/guy/"+String.valueOf(jsonObject.get("id")));  assertEquals(HttpServletResponse.SC_OK, resGet.getStatusCode());  //this is the response "{\"id\":1,\"name\":\"andrew\"}"  JSONObject getGuy = new JSONObject(resGet.getBody().print());  assertEquals(5000L,Long.valueOf(getGuy.get("id").toString()));}我如何才能使僅在測試范圍內運行的 H2database 返回插入的 id，其 de 值例如為 5000。有可能在測試范圍內為實體 Guy 設置星值？謝謝！
